【摘要】：在我國傳統(tǒng)生活中,人們將禽肉、禽蛋視為優(yōu)質(zhì)的餐桌用品和補品。我國家禽飼養(yǎng)量已經(jīng)連續(xù)多年保持世界第一。畜禽養(yǎng)殖方式從小農(nóng)散養(yǎng)模式逐漸轉(zhuǎn)變?yōu)榧s化、規(guī)模化的養(yǎng)殖模式�，F(xiàn)階段養(yǎng)殖戶只重視自身利益,而忽略了糞便處理問題,增加了地區(qū)環(huán)境污染,影響了地區(qū)環(huán)境可持續(xù)發(fā)展,較差的養(yǎng)殖環(huán)境也制約了養(yǎng)殖農(nóng)戶的飼養(yǎng)利潤。大量的飼養(yǎng)給我國日益嚴重的環(huán)境問題帶來了很大的難題。為此需要科技工作者對養(yǎng)殖方式進行改進,提高生產(chǎn)率,降低對環(huán)境的污染。針對我國目前的養(yǎng)殖方式,本著農(nóng)機和農(nóng)藝相融合的理念,本文通過研制適應(yīng)我國現(xiàn)代化、集約化養(yǎng)殖模式的畜禽舍發(fā)酵床翻拋機,利用翻拋機改善畜禽舍環(huán)境,從而促進畜禽生長。本文主要在以下幾個方面進行研究:1.對市場上現(xiàn)有的不同種類翻拋機進行調(diào)研分析,針對實驗場地實際情況,選用合適的翻拋機。對選用的翻拋機進行安裝和調(diào)試,在調(diào)試過程中,為了減少生產(chǎn)成本,設(shè)計并制造了一種橫向移動轉(zhuǎn)運車,可以幫助翻拋機在不同發(fā)酵床運行,方便多發(fā)酵床使用。同時發(fā)現(xiàn),由于翻拋刀片的長度固定,不能很好地對深處發(fā)酵床進行翻拋,使用效率不高,為此對翻拋方式進行了改進;2.根據(jù)調(diào)試翻拋機反饋的優(yōu)缺點和養(yǎng)殖場需求,重新設(shè)計制造了帶深松鏟的翻拋機,翻深可調(diào),最深可達40cm,提高了發(fā)酵床使用效率;3.對選型的翻拋機進行性能試驗測試,分析翻拋機的實際翻深,對比有無翻拋機情況下發(fā)酵床表面空氣中細菌的含量及其與肉鴨生長情況的關(guān)系。結(jié)果表明:利用翻拋機進行翻拋實驗組肉鴨的生長情況明顯高于無翻拋機的對照組肉鴨;4.對比是否帶有深松鏟的翻拋機翻拋前后發(fā)酵床不同深度溫度的變化。試驗表明:經(jīng)翻拋及深松鏟深松后墊料各層的溫度,高于沒有深松鏟深松僅翻拋后的溫度。經(jīng)翻拋及深松鏟深松后墊料底層(35 cm處)溫度為38 ℃,墊料中層(20 cm處)溫度為42 ℃。;沒有深松鏟深松僅翻拋后墊料底層溫度為34 ℃,墊料中層溫度為40 ℃。利用深松鏟對發(fā)酵床底層深松,給底層好氧菌提供更充足的空氣,促進糞便分解。
[Abstract]:In the traditional life of our country, people regard poultry meat and eggs as high-quality table articles and supplements. The quantity of poultry in China has been kept first in the world for many years. Livestock and poultry farming mode gradually changed from small farmers to intensive and large-scale farming model. At present, farmers only attach importance to their own interests, but ignore the problem of faecal disposal, increase regional environmental pollution, affect the sustainable development of regional environment, and the poor breeding environment also restricts the breeding profits of farmers. A large number of feeding to China's increasingly serious environmental problems have brought a great deal of difficulties. Therefore, it is necessary for scientific and technological workers to improve breeding methods, increase productivity and reduce pollution to the environment. In view of the current breeding mode in China, and in line with the concept of combining agricultural machinery and agronomy, this paper develops a fermenting bed flipping machine adapted to the modernization and intensive breeding mode of our country, and improves the environment of livestock and poultry house by using the flipping machine. Thus promote the growth of livestock and poultry. This article mainly carries on the research in the following several aspects: 1. Based on the investigation and analysis of different kinds of flip machines available in the market, the suitable flip machines are selected according to the actual conditions of the experimental site. In order to reduce the production cost, a kind of transporter is designed and manufactured, which can be used in different fermenting beds to facilitate the use of multi-fermenting beds. At the same time, because the length of flip blade is fixed, the deep fermenting bed can not be flipped well, and the efficiency is not high, so the way of flipping is improved; 2. According to the feedback of debugging and throwing machine and the demand of breeding farm, the flip machine with deep spade is redesigned and manufactured. The depth can be adjusted to 40 cm, and the efficiency of fermenting bed is improved. 3. The performance test of the tilting machine was carried out, and the actual depth of the flipping machine was analyzed, and the relationship between the bacterial content on the surface of fermenting bed and the growth of meat duck was compared under the condition of whether there was a flipping machine or not. The results showed that the growth of meat ducks in the experimental group was significantly higher than that in the control group. The temperature changes of fermenting bed before and after flipping with deep spade were compared. The results show that the temperature of each layer is higher than that without deep loosening and deep loosening. The temperature of the bottom layer (35 cm) and the middle layer (20 cm) were 38 鈩，
